Hi 2 all! 🙂

I create easy text array -> oscillator (169 sample points). But sound is not good for me. For example - on a sine waveform (loaded from text array), sound has like a "metallic impurity". So.. And all other captured waveforms, from txt, has this "impurity", and in some notes sounds like a "dirty loops".

Question: What can I do? Maybe I can use any specific commands in OSC code area? Or something special?

Thanks.

i am not much of an expert to this, but i think you need to smooth the waveform. i would suggest sambeans smooth code.

it goes like this:

streamin in; streamout out; stage(0) {out=in;} stage(1) {out=out*0.999+in*0.001;}

Thanks 😉

But, if I use this code, all others waveforms, who has higher frequency, play not correctly.

P.S. I use waveforms from Access Virus B. These wavefroms has a 168 sample points. I want to make oscillator of 64 original waveshapes (from text array to OSC).

hm, then i cant help you at this point, you have to wait for the real experts:)

I guess, this has to do with accuracy. Check the Wave Player module from the toolbox. Use the Counter and Interpolated Read submodules connected to your ArrayMem instead of the Read and Ramp OSC. At least this led to much cleaner sound in my lab.

I found a bug! 🙂

Oscillator (ramp, or others...) in this scheme is a superfluous, and filters too... I changed the scheme of "Array reader", and then I has made resampling for all 64 waveforms to 256x256 format. Sound is as in a source. It's all simple and uses a very low CPU resources.

Changes in schematic of "Array reader":

P.S. Thanks to All! 🙂
